Description
Technical Field
[0001] The present application relates to the technical field of power supply equipment, and in particular to a charging power adapter for digital products. Background Art
[0002] Digital products such as smartphones, tablets, and laptops have become an indispensable part of people's daily lives. These devices have different functions, but they all have a common need - a stable and suitable power supply. The performance of the power adapter, as the key bridge between these devices and the power socket, directly affects the charging efficiency and service life of the device. The power adapter, also known as a power converter or charger, is a small electronic device that provides appropriate voltage and current output to meet the charging or operating requirements of a specific device. Although the current power adapter can already meet the charging needs of most digital products, there are still some shortcomings.
[0003] The existing technology still has the following problems: 1. The traditional power adapter is designed without full consideration of space limitations, and the position of the plug is relatively fixed, which takes up a large space on the socket strip, thereby reducing the space for other electrical appliances. At the same time, the socket strip and the jacks are mostly distributed in hidden locations, and the power adapter is difficult to use under the decoration of some furniture. Some adjustable plugs have poor stability, which makes it difficult to detect changes in the position of the plug in time, which can easily cause safety hazards. At the same time, the power adapter in a hidden place is easily squeezed.
[0004] 2. The internal motherboard assembly of the traditional power adapter is isolated from the outside world by the outer shell, forming a closed space in the inner cavity of the shell, which leads to poor heat dissipation effect of the power adapter when in use. The power adapter will generate heat when working. The charger with poor heat dissipation will generate more heat during operation. If the heat cannot be dissipated in time, the temperature of the power adapter will rise. The temperature increase will cause energy loss, thereby reducing the charging energy efficiency. Specifically, when the temperature of the charger is too high, the components inside the charger may be affected by thermal expansion, and the working efficiency will be reduced, thereby reducing the charging speed. In severe cases, it is easy to explode or even fire. Connecting the mainboard assembly to the external connection does not have a good dustproof effect, so the heat dissipation and dustproof of the traditional power adapter cannot be guaranteed.

[0023] See also Figure 3 and Figure 5 As shown, the adjustment component 4 includes a plug 41, the plug 41 is rotatably connected to the shell 1, the inner cavity of the plug 41 is fixedly connected with an insert blade 42, the outer surface of the plug 41 is provided with a limit groove 43, there are two limit grooves 43, the inner cavity of the shell 1 is slidably connected to a limit block 44, the inner cavity of the shell 1 is provided with a warning mechanism 45, the outer surface of the limit block 44 is provided with a second spring 46, the second spring 46 is located between the limit block 44 and the warning mechanism 45, the limit block 44 is engaged with one of the limit grooves 43, when the space for using the strip or socket is limited, the direction of the plug 41 in the inner cavity of the shell 1 can be adjusted to facilitate adjustment according to the space of the strip or socket, in an environment with limited space, such as behind furniture, In a corner or other narrow space, a traditional fixed-direction plug 41 is often difficult to insert, and may even be unusable due to the wrong direction. The rotatable plug 41 can easily cope with this situation and adapt to different socket hole directions, greatly improving the space utilization efficiency, making the insert blade 42 parallel or vertical to the shell 1, and the limit block 44 and the limit groove 43 are engaged to stabilize the plug 41 in the inner cavity of the shell 1 to prevent the plug 41 from shaking in the inner cavity of the shell 1 during use and causing safety hazards. The second spring 46, under the action of the warning mechanism 45, causes the limit block 44 to limit the plug 41. At the same time, the warning mechanism 45 can generate a warning in the event of an unplanned movement, reminding the user that the limit groove 43 and the limit block 44 are not engaged.
[0024] See also Figure 4 , Figure 5 and Figure 6As shown, the warning mechanism 45 includes an elastic block 451, a hand lever 452 is fixedly installed on the outer surface of the elastic block 451, a first spring 453 is arranged in the inner cavity of the elastic block 451, a limit plate 454 is fixedly connected to the inner wall of the shell 1, screws 455 are arranged at both ends of the limit block 44, a first button 456 is arranged on the outer surface of the elastic block 451, a warning device 457 is arranged on the outer surface of the elastic block 451, a chuck is fixedly installed on the inner wall of the elastic block 451, the first spring 453 is located between the chuck and the limit plate 454, the first spring 453 and the second spring 46 are mainly used to balance the distance between the first button 456 and the screw 455, and the second spring 46 is also used to increase a certain elastic force on the limit block 44, so as to facilitate the limit block 44 and The limiting groove 43 is engaged, so that the adjusted plug 41 is stably connected to the inner cavity of the shell 1, the first button 456 and the screw 455 are aligned, the screw 455 and the limiting block 44 are connected by threads, the first button 456 and the alarm 457 are electrically connected, the pressing of the first button 456 controls the alarm 457 to issue an alarm, the elastic block 451 is slidably connected to the shell 1, and the hand lever 452 is prominently displayed on the outer surface of the shell 1. When the direction of the plug 41 is adjusted, the elastic block 451 can be slid in the inner cavity of the shell 1 by pulling the hand lever 452. At this time, the elastic force of the second spring 46 on the limiting block 44 is reduced, so that the plug 41 is rotated to disengage the limiting groove 43 and engage with the limiting block 44, and the hand lever is released when the plug 41 is rotated ninety degrees. Rod 452, another limit groove 43 is engaged with the limit block 44 again, so that the angle of the plug 41 can be adjusted manually. When the adjustment is not planned, the plug 41 rotates to drive the limit block 44 and the limit groove 43 to disengage. At this time, the plug 41 lifts the limit block 44, thereby driving the second spring 46 to compress. At this time, the limit block 44 moves toward the elastic block 451. The movement of the elastic block 451 drives the screw rod 455 to contact the first button 456, so that the first button 456 is squeezed by the screw rod 455, so that the alarm 457 issues a warning when the first button 456 is pressed, reminding the user that the plug 41 is not stable, or is offset under the action of external force, so as to remind the user to make timely adjustments. In addition, in a narrow space When the device is in use, the device can also issue an alarm when it is squeezed by external force. When other objects approach the device, they first contact the hand lever 452. When pressure is applied to the hand lever 452, the first spring 453 is squeezed. At this time, the first spring 453 contracts between the limit plate 454 and the chuck, and also makes the first button 456 contact the screw 455, so that the first button 456 presses to drive the alarm 457 to sound an alarm. When manual adjustment is required, the hand lever 452 can be pulled. At this time, the distance between the first button 456 and the screw 455 increases, so that even if the limit block 44 moves close to the elastic block 451, the screw 455 and the first button 456 will not contact, thereby achieving no alarm during manual adjustment, and an alarm is issued when external force is not planned.
[0025] See also Figure 7 and Figure 8 As shown, the heat dissipation assembly 6 includes a ventilation hood 61, and a dust cover 62 is fixedly installed on the inner wall of the ventilation hood 61. The dust cover 62 is used to reduce the probability of dust entering the inner cavity of the ventilation hood 61. The inner cavity of the ventilation hood 61 is fixedly connected to a heat dissipation tube 63, and the outer surface of the heat dissipation tube 63 is sleeved with a protective plate 64. A reset buffer mechanism 65 is fixedly installed on the side of the protective plate 64 close to the ventilation hood 61. An alarm mechanism 66 is provided on the outer surface of the protective plate 64, and a moving mechanism 67 is provided on the outer surface of the protective plate 64. A ventilation hole 68 is opened on the outer surface of the heat dissipation tube 63. The ventilation hood 61 is slidably connected to the outer shell 1, and the ventilation hood 61 and the inner wall of the outer shell 1 are tightly fitted. The middle part of the dust cover 62 is provided with The connecting rods are evenly arranged in the inner cavity of the dust cover 62, and there are gaps between the connecting rods. The ventilation holes 68 are evenly arranged on the outer surface of the heat dissipation tube 63. One end of the inner cavity of the heat dissipation tube 63 is hollowed out to the ventilation holes 68. The protective plate 64 partially wraps the ventilation holes 68, so that the ventilation cover 61 is isolated from the outside ventilation by the wrapping of the ventilation holes 68 by the protective plate 64. At the same time, as the heat dissipation tube 63 moves, the ventilation holes 68 are driven to move, so that the ventilation holes 68 are exposed on the outside of the protective plate 64, which is convenient for subsequent ventilation. At the same time, the higher the stability of the inner cavity of the ventilation cover 61, the more ventilation holes 68 are exposed, so that the inner cavity of the ventilation cover 61 can be stably and quickly lowered. There are two reset buffer mechanisms 65, which are respectively located on the protective plate 6 4, the reset buffer mechanism 65 and the outer surface of the ventilation hood 61 are in close contact, the protective plate 64 and the shell 1 are slidably connected, and the ventilation hood 61 and the protective plate 64 are both slidably connected with the line 2. When the device is in use, the mainboard assembly 5 generates a large amount of heat, so that the inner cavity formed by the ventilation hood 61 and the shell 1 is stably increased. At this time, the ventilation hood 61 and the shell 1 are heated and expanded, so that the ventilation hood 61 squeezes the reset buffer mechanism 65, so that the ventilation hood 61 slides on the inner wall of the shell 1. The movement of the ventilation hood 61 drives the heat dissipation tube 63 to move. The movement of the heat dissipation tube 63 exposes the ventilation hole 68 on the outside of the protective plate 64. At this time, the outside air can enter the inner cavity of the shell 1 and the ventilation hood 61 through the ventilation hole 68. , which is convenient for dissipating the heat of the mainboard assembly 5. When the temperature of the mainboard assembly 5 is stable, the ventilation hood 61 is restored to its original position under the action of the reset buffer mechanism 65. At this time, the ventilation hood 61 and the inner cavity of the shell 1 remain in a closed state. The dust cover 62 is used to prevent dust from entering the inner cavity of the ventilation hood 61 from the ventilation holes 68 during ventilation. When the heat in the inner cavity of the ventilation hood 61 is high, the alarm mechanism 66 is used to sound an alarm to remind the user to disconnect for maintenance. The moving mechanism 67 is used for artificial heat dissipation. The protective plate 64 can be slid on the inner wall of the shell 1 as needed to make it easy to always expose the ventilation holes 68 and keep the inner cavity of the ventilation hood 61 in a ventilated state. The user can make a choice according to actual needs.
[0026] See also Figure 8 and Fig. 9As shown, the reset buffer mechanism 65 includes a connecting frame 651, a fixing rod 652 is fixedly installed on the inner wall of the connecting frame 651, a sliding groove 653 is opened on the outer surface of the connecting frame 651, a sliding seat 654 is slidably connected to the outer surface of the fixing rod 652, a third spring 655 is sleeved on the outer surface of the sliding seat 654, a connecting strip 656 is rotatably connected to the inner cavity of the sliding seat 654, and the end of the connecting strip 656 away from the elastic plate 657 is rotatably connected to the elastic plate 657, the connecting frame 651 is fixedly connected to the protective plate 64, the elastic plate 657 is in close contact with the ventilation hood 61, the sliding seat 654 is slidably connected to the sliding groove 653, there are two sliding seats 654, the third spring 655 is located between the two sliding seats 654, and the sliding seats 654 are symmetrically distributed about the middle part of the fixing rod 652, the elastic plate 657 and the connecting frame 651 are parallel, and when the ventilation hood 61 expands due to heat, the ventilation hood 61 moves toward the direction of the protective plate 64 The movement of the ventilation hood 61 drives the ventilation hood 61 to squeeze the elastic plate 657. At this time, the elastic plate 657 moves toward the connecting frame 651. The movement of the elastic plate 657 drives the connecting strip 656 to rotate in the inner cavity of the slide seat 654. The rotation of the connecting strip 656 drives the slide seat 654 to slide in the inner cavity of the slide groove 653. The sliding of the slide seat 654 drives the slide seat 654 to squeeze the third spring 655. At this time, the distance between the elastic plate 657 and the connecting frame 651 is reduced, that is, the distance between the ventilation hood 61 and the protective plate 64 is reduced. Driven by the ventilation hood 61, the ventilation hole 68 is exposed on the outer side of the protective plate 64, so that the mainboard assembly 5 can obtain a good ventilation effect and facilitate heat dissipation. When the temperature inside the ventilation hood 61 is relaxed, the elastic force of the third spring 655 causes the slide seat 654 to move on the fixing rod 652. At this time, the ventilation hood 61 returns to its original position, so that the sealing of the ventilation hood 61 and the inner cavity of the shell 1 is maintained good.
[0027] See also Fig.10 , Fig.11 and Fig.12As shown, the alarm mechanism 66 includes a limit sleeve 661, the inner cavity of the limit sleeve 661 is slidably connected with a telescopic block 662, the outer surface of the telescopic block 662 is provided with a second button 663, the outer surface of the telescopic block 662 is fixedly installed with a connecting block 664, the inner cavity of the connecting block 664 is sleeved with a threaded rod 665, the outer surface of the ventilation hood 61 is fixedly installed with an extrusion rod 666, the outer surface of the protective plate 64 is fixedly installed with a speaker 667, the limit sleeve 661 and the protective plate 64 are fixedly connected, and the second button 663 and the speaker 667 are fixedly installed. 67 is electrically connected, and the pressing of the second button 663 controls the speaker 667 to sound an alarm, the threaded rod 665 and the protective plate 64 are rotatably connected, the extrusion rod 666 is aligned with the second button 663, the connecting block 664 and the threaded rod 665 are threadedly connected, when the ventilating hood 61 moves, the extrusion rod 666 is driven to move, and the extrusion rod 666 moves to drive the extrusion rod 666 to contact the second button 663, when the second button 663 is squeezed by the extrusion rod 666, the speaker 667 sounds an alarm, reminding the user that the ventilating hood is now 61 The inner cavity temperature is high, and the use of the device can be stopped. The distance between the second button 663 and the extrusion rod 666 can be adjusted to ensure that the second button 663 does not contact the extrusion rod 666 when the ventilation hole 68 is dissipating heat normally. At this time, the connection block 664 is moved by rotating the threaded rod 665. The movement of the connection block 664 drives the telescopic block 662 to slide in the inner cavity of the limiting sleeve 661. The movement of the telescopic block 662 drives the second button 663 to move. The movement of the second button 663 changes the distance between the second button 663 and the extrusion rod 666, thereby ensuring that the device will not sound an alarm under normal ventilation. When the inner cavity of the ventilation hood 61 is too high and the ventilation of the ventilation hole 68 cannot be relieved, the ventilation hood 61 continues to move, so that under high temperature expansion, the ventilation hood 61 continues to move to drive the extrusion rod 666 to contact the second button 663, and the user is reminded to stop using it in time, which can reduce this potential risk of damage, thereby extending the service life of the charger, preventing the power adapter from overheating, and avoiding safety problems such as explosion or fire of the power adapter.
[0028] See also Fig.12 and Fig.13As shown, the moving mechanism 67 includes a connecting seat 671, the inner cavity of the connecting seat 671 is slidably connected with an insertion rod 672, the outer surface of the insertion rod 672 is fixedly installed with a fixing ring 673, the outer surface of the insertion rod 672 is sleeved with a fourth spring 674, the fourth spring 674 is located between the inner wall of the connecting seat 671 and the fixing ring 673, the outer surface of the shell 1 is provided with a socket 675, the insertion rod 672 and the socket 675 are plugged together, the connecting seat 671 and the protective plate 64 are fixedly connected, when the user needs to keep the inner cavity of the ventilation hood 61 ventilated for a long time, the insertion rod 672 is pulled to disengage the insertion rod 672 and the socket 675, at this time, the connecting seat 671 is moved to reduce the distance between the protective plate 64 and the ventilation hood 61, so that the ventilation hole 68 will be exposed, and the position of the protective plate 64 can be adjusted according to needs. When it reaches the appropriate position, release the plug rod 672 and drive the fixing ring 673 to move under the elastic force of the fourth spring 674, so that the plug rod 672 is engaged with the socket 675 again, so as to fix the position of the protective plate 64 on the inner wall of the shell 1. In this way, long-term ventilation and heat dissipation of the inner cavity of the ventilation hood 61 can be achieved. The user can choose long-term ventilation according to needs, or drive the ventilation hood 61 to move and dissipate heat by itself when the mainboard assembly 5 generates heat. For example, in a dusty site, the protective plate 64 can be selected to cover the ventilation hole 68, so that the power adapter can dissipate heat by itself when high temperature is generated. In a site with a good environment, the ventilation hole 68 can be leaked to maintain long-term ventilation, and the dustproof of the dust cover 62 can be combined to achieve the dual effects of heat dissipation and dustproof, thereby meeting the needs of various application scenarios.
[0029] In summary, when in use, the connector 3 is inserted into the interface of the digital product, the adjustment component 4 is plugged into the socket, and the angle of the adjustment component 4 on the housing 1 is adjusted according to the space of the socket or the spatial distribution of the socket strip. The line 2 is used for the electric energy to flow between the power adapter and the device, thereby realizing charging. The heat dissipation component 6 is used to protect the motherboard assembly 5 from dust and heat. When the space for the socket strip or the socket is limited, the direction of the plug 41 in the inner cavity of the housing 1 can be adjusted to facilitate adjustment according to the space of the socket strip or the socket. The plug 41 can be rotated to It can easily cope with this situation and adapt to different socket hole directions, greatly improving the space utilization efficiency, making the insert blade 42 parallel or perpendicular to the shell 1, and the stop block 44 and the stop groove 43 are engaged to stabilize the plug 41 in the inner cavity of the shell 1 to prevent the plug 41 from shaking in the inner cavity of the shell 1 during use and causing safety hazards. The second spring 46, under the action of the warning mechanism 45, causes the stop block 44 to limit the plug 41. At the same time, the warning mechanism 45 can generate a warning in the case of unplanned toggle, reminding the user that the stop groove 43 and the stop block 44 are not engaged. When the device is in use, When the mainboard assembly 5 generates a large amount of heat, the inner cavity formed by the ventilation cover 61 and the shell 1 rises steadily. At this time, the ventilation cover 61 and the shell 1 expand due to the heat, so that the ventilation cover 61 squeezes the reset buffer mechanism 65, so that the ventilation cover 61 slides on the inner wall of the shell 1. The movement of the ventilation cover 61 drives the heat dissipation tube 63 to move. The movement of the heat dissipation tube 63 exposes the ventilation holes 68 on the outside of the protective plate 64. At this time, the outside air can enter the inner cavity of the shell 1 and the ventilation cover 61 through the ventilation holes 68, which is convenient for dissipating the heat of the mainboard assembly 5. When the temperature of the mainboard assembly 5 is stable, The reset buffer mechanism 65 restores the ventilation hood 61 to its original position. At this time, the ventilation hood 61 and the inner cavity of the shell 1 remain in a closed state. The dust cover 62 is used to prevent dust from entering the inner cavity of the ventilation hood 61 from the ventilation holes 68 during ventilation. When the heat in the inner cavity of the ventilation hood 61 is high, the alarm mechanism 66 is used to sound an alarm to remind the user to disconnect for maintenance. The moving mechanism 67 is used for artificial heat dissipation. The protective plate 64 can be slid on the inner wall of the shell 1 as needed to facilitate the ventilation holes 68 to be always exposed, thereby keeping the inner cavity of the ventilation hood 61 in a ventilated state.
